IMPROVEMENT lN COFFEE-ROASTERS.

The Schedule referred to in these Letters Patent and making part of the same- Io all 'whomtt 'may concern Be it known that I, HARLOW M. GILBERT, of Ada,

in the county ot' Hardin and inthe State of Ohio, have' invented a new and useful Improvement in Coffee- Roasters; and I do hereby declare that the following is a full, clear, and exact description thereof', 'ref' erence being had to the-annexed drawing making part of this specification, in which-.

This invention relates to devices for roasting coffee; and

1t consists in combining with an ordinary skillet or frying-pan a cdnicalcap, containing an agitator, which is to be placed'upon such a skillet when coffee is to be fbrowned or roasted therein, for the purposes of preventing the escape of fumes, risiugrfrom such coffee,

and `retaining the aroma therein. l

.To enable those skilled in the art to make and use myyinvention, I will proceed to describe its construe? tion and operation.

A represents askillet, having a handle, A', by which Io'manipulate it. Its rim is formed with a shoulder and annular vertical dan ge, a, which embraces the lowerend of the conical cap B when the latter is placed upon it, such cap being provided with a collar, b, which rests upon the upper edge-of the ilange a of the pan.

The cap is held downv on the pan by hooks br, as"

shown in iigs. 1 and 2.

In the cap an opening is made at b2, through which the coffee may beinspected or introduced into the pan, said opening being closed by a slide, B.

C represents a vertical shaft, which has its bearings in an aperture in the apex of the conical cap, and a crossbar, B2, stretched diametrically across the lower end of the same. i f

The upper end of the shaft projects through the cap, and is provided there with a crank, O1, by which to turn it; and near its lower.'end, which may rest upon the bottom of the skillet, two arms, C2 G2, are'secured to it at right angles to each other, forming an agitator by which the coffee is constantly stirred while being roasted, to prevent its burning.

"What I claim as my invention, and desire to secure by Letters Patent, is-

The conical top Bfhaving door B1, agitator G C G2.

collar b, and hooks b1, in combination with the skillet A,

having the ange a, all constructed and arranged substantially as described.
